MagnaFlow Conv DF 06-09 Cadillac STS 4.4L Driver Side

If you're working on a 2006-2009 Cadillac STS with the 4.4L engine and need to replace the driver side catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to meet or exceed Federal emissions requirements set by the EPA, helping you keep that check engine light off and your vehicle running cleanly. Magnaflow uses advanced 3D scanning to ensure this converter matches the original equipment in terms of fit and function, so you won't have to worry about it not lining up correctly.

What sets this converter apart is its construction and design. The tubing is mandrel-bent, which means it maintains a consistent diameter throughout, eliminating restrictions and allowing exhaust gases to flow freely. This is crucial for maintaining factory performance and fuel efficiency. The entire unit is built from 16-gauge 409 stainless steel, which is known for its strong resistance to corrosion, giving you confidence in its long-term durability. The welds are also made from 308 stainless steel using MIG welding, which helps reduce the chance of leaks. Magnaflow also includes the necessary gaskets and hardware, making the installation process smoother and avoiding the need to reuse old, potentially corroded parts.

This is a direct-fit converter, meaning it's designed to bolt right into place without any cutting or welding required, simplifying the installation for a DIYer with the right tools. It's compliant with Federal/EPA emission systems for OBDII vehicles. Please note that this converter is not CARB approved and cannot be shipped to California.
